I propose a method identification of structural vector autoregressions (SVARs) and simultaneous equations models (SEMs) with orthogonal structural shocks using testable identification restrictions. If some sparsity conditions are satisfied, the method produces a set of testable inclusions and exclusions, sufficient for the full identification. The method stems from the theory of probabilistic graphical models and from the theory of identification of SVARs and SEMs, merging them into a unified approach. In the application example, I estimate a SVAR monetary model of the US economy with 6 variables, where all but one identifying restrictions are testable. The method produces relatively narrow confidence intervals for the impulse-response functions, does not generate any anomalies such as the price puzzle, and reveals importance of informational channels through which news about structural shocks spread throughout the economy.

This paper provides nested sets and vector representations of knockout tournaments. The paper introduces classification of probability domain assumptions and a new set of axioms. Two new seeding methods are proposed: equal gap seeding and increasing competitive intensity seeding. Under different probability domain assumptions, several axiomatic justifications are obtained for equal gap seeding. A discrete optimization approach is developed. It is applied to justify equal gap seeding and increasing competitive intensity seeding. Some justification for standard seeding is obtained. Combinatorial properties of the seedings are studied.

The well-known modern dimensional models of affect include two or three dimensions. They are typically based on self-reports using English emotion terms. It remains unclear to what extent these models can be applied to different cultures and languages. The present study is aimed at finding the dimensions underlying the descriptions of emotional states in Russian and suggests a structural model of affect based on these findings. At the first stage, a comprehensive list of Russian nouns denoting emotional states was compiled. It comprised 330 words and was reduced to a list of 56 words. At the second stage, participants rated their emotional states using this list. The exploratory factor analysis yielded three dimensions that underlay participant descriptions of the emotional states – negative affect with low activation, positive affect with high activation, and tension. This model is compared to other structural models of affect and its special features are discussed. This model can be used for developing Russian-based measures for the assessment of mood.

The causes of everyday errors made by most people remain largely unknown. In order to investigate spontaneous lapses in attentional processing a new task was designed. This task creates an increased attentional load because it is based on impeded decision making involving both stimuli feature binding and response selection. Participants made errors  in 9.6 ± 1.1% of trials and re-sponse omissions in 5.4 ± 0.7% of trials. In the ERP pattern the N1 and P2 peaks were well pronounced, while P3 peak was almost indistinguishable. The P2 peak was greater in trials with errors and response omissions compared to correct responses. The results obtained substantiate the hypothesis that attentional lapses may be a consequence of mind-wandering, which may compete with the overt task for the attentional resources.

This paper analyzes the relationship between support of democracy and attitudes to human rights: in particular, support for gender equality in the countries covered by the first wave of the Arab Barometer project. We used cluster analysis and negative binomial regression modeling to show that, unlike in most countries of the world, the correlation between support of democracy and gender equality is very low in Arab countries. There is a group of people in the region who support both democracy and gender equality, but they are a small group (about 17% of the population) of elderly and middle-aged people characterized by higher education and social status. A substantial number of poorly educated males express support for democracy, but not for gender equality. Many people (especially young males aged 25-35 in 2007) are against both gender equality and democracy. Younger people tend to be both better educated and more conservative -- those belonging to the 25-34 age group are the most patriarchal in their gender attitudes. Controlling for age, education still has a positive effect on gender equality attitudes. Nevertheless, this phenomenon probably means that there are two simultaneous processes going on in the Middle East. On the one hand, people are becoming more educated, urbanized etc., which means the continuation of modernization. On the other hand, we observed a certain retrogression of social values.

This paper considers two issues. First, it evaluates the changes in Russia’s investment climate in 2012-2014 after the announcement of an ambitious governmental program to improve the conditions for doing business. Second, because the relevant reforms were personally initiated by Vladimir Putin, we carried out a survey experiment designed to find out how references to a popular politician influence respondents’ opinions about the business climate. We used the data of a large-scale survey of top managers in Russian manufacturing sector conducted in July-October of 2014. Contrary to the World Bank report, Easy Doing Business, our empirical data shows that there was practically no improvement in the investment climate in Russia in 2012-2014. Also contrary to the results of population surveys showing extremely high public support for Vladimir Putin after Crimea’s accession to Russia, our survey experiment demonstrated that referring to the President Putin as the initiator of business climate reform improves assessments of the business climate change only slightly. However, the effect of reference to the President’s initiative differs significantly for firms from different size groups – we revealed no effect of question wording in the group of small firms, much higher share of non-answers in the group of large firms and a significant increase in the share of positive assessments of business climate among mid-size firms when Vladimir Putin was mentioned.

The paper demonstrates the results of a study which aimed to identify the relationship between individual values and attitude towards innovation. 380 respondents, young and adult representatives of the Russian population, took part in the research. The respondents belonged to the younger generation (under 25 years old) or to the adult generation (over 45 years old). The principal instrument used was the method of questionnaires. The methodic inventory consists of three main blocks oriented to the study of the following constructs: the PVQ-R method of measuring individual values (Schwartz et al., 2011) and the method of “Self-assessment of innovative qualities of a personality” (Lebedeva, Tatarko, 2009).The goal of the research is to reveal the age differences in values and attitudes towards innovation, and to find out which values determine positive or negative attitude towards innovations among representatives of different generations of Russians. The younger generation values " Self-Direction Thought", "Stimulation", "Achievement", " Power Dominance" stimulate the adoption of innovations.

This paper presents a new approach to the measurement of attitudinal polarization for cross-national or repeated cross-sectional studies. The proposed approach is a two-stage one. At the first step, order-constrained Latent Class Analysis (LCA) is used to identify a categorical latent construct underlying a set of observed items. Basing on the best LCA solution, class membership is assigned for each individual in the sample. At the second step, a broad family of categorical polarization indices may be computed for that categorical latent scale in respect to any grouping variable of interest (e.g., country of living, or wave of study). The data from the 4th wave of the European Values Study are used, and polarization between survival and self-expression values in 28 European countries is measured. The resulting polarization scores are used to test a hypothesis assuming positive aggregate-level association between values polarization and support for radical right parties and ideologies

The paper is focused on the existence problem of attractors for foliations. Since the existence of an attractor is a transversal property of the foliation, it is natural to consider foliations admitting transversal geometric structures. As transversal structures are chosen Cartan geometries due to their universality. The existence problem of an attractor on a complete Cartan foliation is reduced to a similar problem for the action of its structure Lie group on a certain smooth manifold. In the case of a complete Cartan foliation with a structure subordinated to a transformation group, the problem is reduced to the level of the global holonomy group of this foliation. Each countable automorphism group preserving a Cartan geometry on a manifold and admitting an attractor is realized as the global holonomy group of some Cartan foliation with an attractor. Conditions on the linear holonomy group of a leaf of a reductive Cartan foliation sufficient for the existence of an attractor (and a global attractor) which is a minimal set are found. Various examples are considered.

The 2014 Australian presidency took place against the backdrop of multiple challenges in both global economy and international politics, with Ukrainian crisis, Syrian conflict, Islamic State, and Ebola. Thus, despite being an economic forum, the G20 could not avoid addressing these issues, with discussions taking place during the bilateral meetings and on the sidelines of the forum. The article attempts to analyze the Australian G20 Presidency within a functional paradigm, assessing G20 performance on the three main objectives of plurilateral summitry institutions: strengthening capacity for political leadership to launch new ideas and overcome deadlocks; reconciling domestic and international pressures; and consolidating collective management. The analysis revealed that, despite a number of setbacks, the 2014 Australian presidency managed to steer the G20 members’ cooperation on the four major pillars of the institution’s agenda, reflecting a consistently high level of the G20 commitment to fulfilling its key mission of ensuring strong, sustainable, balanced and inclusive growth.  The research was carried out with financial support of Russian Humanities Research Foundation within the framework of a research project “Elaborating a Supply – Demand Model to Balance External Demand and National Priorities in the Presidency Proposals for Agenda in G20, G8 and BRICS”, project  №12-03-00563.

In this paper a Kalman-filter type model is used to extract a global stochastic trend from discrete nonsynchronous data on daily stock market index returns from different markets. The model allows for the autocorrelation in the global stochastic trend, which means that its increments are predictable. It does not necessarily mean the predictability of market returns, since the global trend is unobservable. The performance of the model for the forecast of market returns is explored for three markets: Japan, UK, US.

The paper presents a Universal Dependencies (UD) annotation scheme for a learner English corpus. The REALEC dataset consists of essays written in English by Russian-speaking university students in the course of general English. The essays are a part of students' preparation for the independent final examination similar to the international English exam. While adjusting existing dependency parsing tools to a learner data, one has to take into account to what extent students' mistakes provoke errors in the parser output. The ungrammatical and stylistically inappropriate utterances may challenge parsers' algorithms trained on grammatically appropriate written texts. In our experiments, we compared the output of the dependency parser UDpipe (trained on UD-English 2.0) with the results of manual parsing, placing a particular focus on parses of ungrammatical English clauses. We show how mistakes made by students influence the work of the parser. Overall, UDpipe performed reasonably well (UAS 92.9, LAS 91.7). The following cases cause the errors in automatic annotation a) incorrect detection of a head, b) incorrect detection of the relation type, as well as c) both. We propose some solutions which could improve the automatic output and thus make the assessment of syntactic complexity more reliable.

The article deals with the method of automatic detection of authors ' gender identity on the material of fiction prose of 1980-2000. During this period, there is a special construct, called "women's prose", which is characterized by a special genre and stylistic originality. We set ourselves the task to find out whether the concept of “women's prose” refers only to the non-text reality or is clearly reflected at the level of language. We have collected corpus of texts 1980-2000 and conducted that identified the most effective machine learning algorithms for the classification of male and female prose.

The present paper applies Multiple Correspondence Analysis to test the validity of an existing theoretical model of the phonological system of Russian Sign Language (RSL). We show that comparing the importance of phonological features using ratio plots and MCA is a promising way of revealing non-binary oppositions in phonological systems of human languages irrespective of modality.

In 2007, Dubouloz introduced Danielewski varieties. Such varieties general- ize Danielewski surfaces and provide counterexamples to generalized Zariski cancellation problem in arbitrary dimension. In the present work we describe the automorphism group of a Danielewski variety. This result is a generalization of a description of automorphisms of Danielewski surfaces due to Makar-Limanov.
